摘要： The present invention provides a separation membrane that is suitable for separating an acid gas from a gas mixture containing the acid gas and has a high acid gas permeability. A separation membrane (10) of the present invention includes: a separation functional layer (1); a porous support member (3) supporting the separation functional layer (1); and an intermediate layer (2) disposed between the separation functional layer (1) and the porous support member (3), and including a matrix (4) and nanoparticles (5) dispersed in the matrix (4).
